About Symmetry
Symmetry is a security management system that provides a single integrated solution for all key elements
of site security, including access control, intruder detection, guard patrolling, intercom management, CCTV
monitoring, video recording and video playback. Symmetry is able to match the requirements of any size of
organization, from a small office requiring just a few access-control readers, to a large company requiring
the full range of automated security systems spread over multiple sites and countries.
Symmetry has a modular approach to system design, which allows the hardware and software components
to be selected to match the exact needs of the site. As the organization grows or requirements change,
additional components can be easily added to extend the capabilities and size of the system.
A key feature of Symmetry is that it brings together all key elements of site security within a single fully-
integrated solution. This allows the different components to work together to enhance site security. For
example, video recordings can be started automatically by intrusion alarms, lights can be switched on by
access-control transactions, and doors can be automatically unlocked by a fire alarm. Integration is often a
key business requirement, not only to improve the capabilities of the system, but also to enhance operator
efficiency.
Symmetry is supplied with the Security Management System software (SMS software), which can run on a
standalone PC, or in a client/server networked architecture. The software enables an operator to configure
the system, enter card holder details, design and print badges, view video, manage visitors, operate
hardware, view alarms, produce reports, manage the system, and much, much more. The SMS software
provides single user interface, irrespective of the modules included. Features such as alarm management,
graphics display and report generation are common across all modules, allowing operators to monitor and
control all equipment from a single user interface.
Symmetry M2150
Symmetry M2150 is a range of database units, controllers and other hardware components. The M2150
hardware provides all the necessary connections for card readers and door furniture, including release
devices, bypass circuits, door monitors and exit-request buttons. The M2150 hardware carries out a wide
range of tasks, such as granting or denying access, running scheduled and trigger commands, logging
transactions and monitoring sensors. An example of an M2150 system is shown in Figure 1-1.
